Heap Leaching of Gold and Silver Ores

· Processing ore in a mill has higher operating costs and requires more capital investment than processing it in a heap A heap leach typically achieves ∼25% less gold recovery than a mill The operating cost plus debt service for a medium sized mill 3000 t/d is typically $39/t of ore treated whereas the comparable cost for the heap is $19/t equating to a differential operating cost plus
